| 1. | The lectin exhibited potent mitogenic activity toward mouse splenocytes . xylaria hypoxylon lectin ( xhl ) , with a molecular weight of 29kda , was isolated from the fruiting bodies of xylaria hypoxylon
从鹿角炭角菌( xylariahypoxylon )子实体中，纯化到了一个分子量29kda ，由两个相同分子量为14 . 4kda亚基组成的凝集素。 |
| 2. | With the modification of the method , the technique of differential display ( dd ) has become a very useful method for elucidating changes in gene expression in response to temporal de - velopment , disease and mitogenic stimulants
在过去几年里，出现了许多技术方面的改进，主要集中在增加对于差异表达基因鉴定的效率和降低对于基因鉴定的工作量两个方面。 |
| 3. | Together the results show that chemical modification of the lectin can affect heamagglutination and mitogenic activity separately . this indicates that the polygonatum cyrtonema hua . lectin ii has at least two active centres which play different roles in determining its activity
研究黄精凝集素n抗艾滋病毒fa琴1和hi从2对cem ( t细胞淋巴瘤细胞系)和th . 4 (小鼠神经细胞系)的感染中的作用发现。 |
| 4. | With a mitogenic stimulus such as ph , retrorsine - injured hepatocytes undergo apoptosis and are selectively removed from the hepatic parenchyma . the emergence and rapid expansion of a population of small hepatocyte - like progenitor cells ( shpcs ) contribute to the restoration of live mass after ph
肝脏再生过程中，肝实质中会产生一种集落样增殖的“小肝细胞样原始细胞” ( smallhepatocyte - likeprogenitorcells , shpcs ) ，并通过这种细胞的增殖和分化完成肝脏的再生。 |
| 5. | Human insulin - like growth factor - 1 ( igf - 1 ) is a basic polypeptide containing 70 amino acid residues . its truncated form , i . e . des ( l - 3 ) igf - 1 , is three residues shorter than the intact form at n - terminal . igf - 1 has many biological actions such as mitogenic , metabolic effects and others
<中文摘要> =人胰岛素样生长因子1 （ insulin - likegrowthfactori ， igf - 1 ）是一个由70个氨基酸组成的碱性多肽，其截短型比完整型的n端少了三个氨基酸（甘氨酸、脯氨酸、谷氨酸） 。 |
| 6. | Pcl ii had two mutations in nueleotide sequences and amino acid sequence compared with that of natural pcl ii . the effect of chemical modification of amino acid residues upon haemagglutination and mitogenic activity toward t - lymphocytes was investigated . modification of tyrosine ( 1 - acetylimidazole and 4 - nitrobenzenesulphonyl fluoride ) did not alter haemagglutination but decreased mitogenic activity by about one half
采用不同的方法对酪氨酸( tyr )进行了修饰:用勺r酚经基专一性试剂对硝基苯磺酞氟( nbsf )修饰pcln ，导致pcln促淋巴细胞有丝分裂活性大幅下降，表明巧r的酚经基对于此活性是必需的。 |
